Abstract: Process for heat recovery from cleavage gases in the preparation of vinyl chloride by cleavage of 1,2-dichloroethane, wherein cleavage of the 1,2-dichloroethane is carried out at a pressure at which the cleavage gases leave the reactor under a pressure in the range from 5 to 30 bar, the cleavage gases are quenched by direct cooling and the resulting vapour is passed through heat exchangers.
